1,Install the groove of the collet into the eccentric circle position of the nut.Push the collet in the direction of the arrow until you hear a click, which meansthe collet
is inthe right place.
2,Attach the collet to the toolholder and make sure the tool is in the ritht place.3,Put the nut on the tool holder and lock it with a wrench.After screwing the nut off the tool shank, pull out the tool and push in from thefront of the collet and simultaneously press down against the eccentric circle,pushing
the collet diagonally until the collet and nut break apart.1.lmproper assembly may damage the accuracy of the collet and may result indamage to the nut .
2.Only use the matching spring collet for the nut .
3.Clamping of tools beyond the clamping range is prohibited.
1.Tool Holders: HSK tool holder ,BT tool holder ,SK/DAT tool holder ,NT tool holder ,CAT tool holder2.Holder Accessories : ER collets ,Pull stud ,Spanner ,Locking Device ,Collet chuck ,Drill chuck
3.Boring head:Boring head set ,Fine boring head , Rough Boring head ,Boring head shank
4.Face Milling Cutter :Face milling cutter ,End Milling Cutter
